A study on the characteristics of the marine boundary layer over Indian Ocean with ORV Sagar Kanya cruise # 120 during 1997

The CLASS system observations of wind speed, wind direction, temperature an d moisture at different pressure levels taken during the pre-INDOEX (Indian Ocean Experiment) cruise # 120 were used for the study, This article prese nts a study of marine boundary layer (MBL) characteristics, such as turbule nt kinetic energy, MBL height, eddy diffusivity, etc, over the Indian Ocean using a multilevel one-dimensional PBL model with one and a half order TKE -epsilon closure scheme, The model also generates the vertical profiles of zonal wind, meridional wind, potential temperature and specific humidity. T he model simulations are compared with the observations and the statistical analysis, viz, correlation coefficient; the RMS error is found to be satis factory.
